The freeCapacityArea parameter defines the free capacity area to use for the virtual disk. If a disk group has several free capacity areas, you can use this parameter to identify which free capacity area to use for virtual disk creation. You do not have to assign the entire capacity of the physical disks to the virtual disk. Assign any unused space to another virtual disk at another time. The userLabel, capacity, owner, and segmentSize parameters are the same as in the previous versions of the create virtualDisk command. Enclosure Loss Protection The enclosureLossProtect parameter is a boolean switch that turns enclosure loss protection on or off. To work properly, each physical disk in a virtual disk group must be in a separate enclosure. Enclosure loss protection is set under the following conditions: • You assign the physical disks. • The RAID controller module assigns the physical disks. The following table shows possible results for the enclosureLossProtect parameter. The results depend on whether you assign the physical disks or the RAID controller module assigns the physical disks.
